Gas stove-coal stove-water heater energy conservation and emission reduction device

The invention relates to a gas stove-coal stove-water heater energy conservation and emission reduction device. The gas stove-coal stove-water heater energy conservation and emission reduction device has the following two benefits: firstly, with the adoption of the technology, time consumed by the gas stove and the coal stove in the cooking process in daily life is reduced by half; and secondly, with the adoption of the technology, high temperature gas of hundreds of degrees produced in the gas and coal combustion process is changed into low temperature gas of tens of degrees to be discharged into the air, namely, the energy conservation and emission reduction water heater device is realized. The device is further characterized in that a heat-retaining barrel is arranged for collecting hot gas produced by gas and coal combustion, so that a pot is surrounded by a lot of hot gas, the heat degree of food in the pot is increased, redundant hot gas is conveyed into the water heater, hot gas of hundreds of degrees
